Definitions

  • the present invention relates to a field of overhead wire inspection that measures wear of an overhead wire by capturing an image of the width of the lower surface of the overhead wire from the top of a train roof and by performing image processing on the image.
  • the present invention particularly relates to an overhead wire wear measurement device and an overhead wire wear measurement method that determine a remaining-diameter-equivalent value for an overhead wire the pantograph-sliding surface of which is partly oblique (an unevenly worn overhead wire), the remaining-diameter-equivalent value serving as an index to know whether the overhead wire has reached the end of its life.
  • Fig. 8 shows a schematic, cross-sectional view of an overhead wire. Due to a contact with a pantograph (not shown), an unworn overhead wire 5 shown in Fig. 8(a) wears in such a manner that its lower surface becomes parallel to the horizontal plane as shown in Fig. 8(b) or becomes oblique to the horizontal plane as shown in Fig. 8(c) .
  • a part of an overhead wire that has worn away to be parallel to the horizontal plane is referred to as a horizontally worn part 5a
  • a part of an overhead wire that has worn away to be oblique to the horizontal plane is referred to as an obliquely worn part 5b.
  • the overhead wire 5 may also come to have a wear part in a wear state called uneven wear formed by the horizontally worn part 5a and the obliquely worn part 5b, as shown in Fig. 8(d) .
  • Patent Document 1 describes an overhead wire measurement method for measuring the amount of wear of the overhead wire 5 having the horizontally worn part 5a like the one shown in Fig. 8(b) .
  • Patent Document 2 describes an overhead wire measurement method for measuring the amount of wear of the overhead wire 5 having the obliquely worn part 5b like the one shown in Fig. 8 (c) .
  • Patent Document 3 discloses use of laser light to measure uneven wear of the overhead wire 5 like the one shown in Fig. 8(d) .
  • Patent Document 3 converts the horizontally worn part 5a and the obliquely worn part 5b into binary representations based on the difference in the intensity of reflected laser light, and as shown in Fig. 9 , calculates a remaining diameter H A of the horizontally worn part 5a and a remaining diameter HB of the obliquely worn part 5b using the widths of the horizontally worn part 5a and the obliquely worn part 5b and a prepared remaining diameter table.
  • the document JP 2009 274508 A (which corresponds to above mentioned Patent document 3) discloses an overhead wear measurement device according to the preamble of claim 1.
  • Non-Patent Document 1 " Overview of Electricity for railway Engineers, Series 2 of Electric Train Lines, Train Wires" multi-authored by a writing group, JAPAN RAILWAY ELECTRICAL ENGINEERING ASSOCIATION, November 10, 1998, pp. 4 to 5 and 32 to 33
  • the overhead wire 5 may break when decreased in tensile strength.
  • the tensile strength of the overhead wire 5 correlates with the area of a remaining cross section of the overhead wire 5, and therefore a remaining diameter calculated by measurement of an overhead wire should be set such that the remaining diameter correlates with the remaining cross-sectional area.
  • an appropriate index of the wear state of an unevenly worn overhead wire having the horizontally worn part 5a and the obliquely worn part 5b should be represented not by the two remaining diameters, namely the remaining diameters of the horizontally worn part 5a and the obliquely worn part 5b, but by a single value based on the cross-sectional area (such a value is hereinafter referred to as a remaining-diameter-equivalent value).
  • the conventional overhead wire measurement methods described above can obtain the remaining diameter values of the horizontally worn part 5a and the obliquely worn part 5b, but cannot obtain a single remaining-diameter-equivalent value which is based on the remaining cross-sectional area and takes the horizontally worn part 5a and the obliquely worn part 5b into account, particularly for the overhead wire 5 in an unevenly worn state. It has therefore been difficult to find an accurate tensile strength of the overhead wire 5.
  • the present invention aims to provide an overhead wire wear measurement device and an overhead wire wear measurement method capable of calculating a single remaining-diameter-equivalent value which is based on the remaining cross-sectional area and takes a horizontally worn part and an obliquely worn part into account.
  • an overhead wire wear measurement method for finding a remaining diameter of an overhead wire by capturing an image of a lower surface of the overhead wire, which comes into contact with a pantograph, with a wear measurement camera disposed on a roof of a train and by performing image processing on the captured image of the lower surface of the overhead wire, characterized in that a remaining diameter of a horizontally worn overhead wire having only a horizontally worn part is calculated as a remaining-diameter-equivalent value for an unevenly worn overhead wire having the horizontally worn part and an obliquely worn part, the horizontally worn overhead wire having the same cross-sectional area as the unevenly worn overhead wire.
  • An overhead wire wear measurement method is characterized in that the method comprises the steps of:
  • An overhead wire wear measurement device is an overhead wire wear measurement device comprising a wear measurement camera configured to be disposed on a roof of a train and an image processing unit configured to find a remaining diameter of an overhead wire by causing the wear measurement camera to capture an image of a lower surface of the overhead wire, which comes into contact with a pantograph and by performing image processing on the captured image of the lower surface of the overhead wire, characterized in that the image processing unit includes a remaining-diameter-equivalent value calculation processing unit configured to calculate a remaining diameter of a horizontally worn overhead wire having only a horizontally worn part, as a remaining-diameter-equivalent value for an unevenly worn overhead wire having the horizontally worn part and an obliquely worn part, the horizontally worn overhead wire having the same cross-sectional area as the unevenly worn overhead wire.
  • An overhead wire wear measurement device is characterized in that the image processing unit includes
  • An overhead wire wear measurement device and an overhead wire wear measurement method can find an accurate tensile strength of even an unevenly worn overhead wire having a worn part formed by a horizontally worn part and an obliquely worn part by calculating a remaining-diameter-equivalent value taking a remaining cross-sectional area into account.
  • FIG. 1 to 7 An embodiment of an overhead wire wear measurement device according to the present invention is described using Figs. 1 to 7 .
  • a line sensor camera (wear measurement camera) 2 is disposed on the roof of an inspection vehicle (train) 1 as image input means that captures an image of the lower surface of an overhead wire 5, which comes into contact with a pantograph (not shown) .
  • An image processing device (image processing unit) 3 and a recording device 4 are disposed inside the inspection vehicle 1.
  • the line sensor camera 2 is oriented in such a manner as to capture an image of an area vertically above the inspection vehicle 1 with its scanline direction being the same as the direction of crossties for rails 6, or in other words, orthogonal to the travel direction of the inspection vehicle 1. With such an orientation, a scanline of the line sensor camera 2 crosses the overhead wire 5. Signals representing the image of the lower surface of the overhead wire 5 captured by the line sensor camera 2 are inputted to the image processing device 3.
  • the image processing device 3 includes a line sensor image creation unit 3a, an overhead wire center point position calculation processing unit 3b, a division point positions calculation processing unit 3c, a wear cross-sectional area calculation processing unit 3d, a remaining-diameter-equivalent value calculation processing unit 3e, and memory M1, M2 as storage means.
  • the image processing device 3 calculates a remaining-diameter-equivalent value H (see Fig. 7(b) ) for an overhead wire with a worn part by performing image processing on the image signals received from the line sensor camera 2.
  • the image signals received from the line sensor camera 2 are arranged chronologically by the line sensor image creation unit 3a and stored in the memory M1 as a line sensor image I (see Fig. 4 ) (Step S1).
  • the pixel positions of points on the line sensor image I shown in Fig. 4 are, for example, set automatically by the system performing the image processing on the line sensor image I or by a user with a GUI, the points on the line sensor image I being the left end p1 of the overhead wire, the left end p2 of a horizontally worn part (an end portion of the horizontally worn part), the division point p3 between the horizontally worn part and an obliquely worn part, the right end p4 of the obliquely worn part (an end portion of the obliquely worn part), and the right end p5 of the overhead wire (which respectively correspond to points P1, P2, P3, P4, and P5 shown in Fig. 6 and are hereinafter referred to simply as division points p1 to p5).
  • Camera parameters (focal length, the number of sensor elements, and sensor width) are preset.
  • Step S1 the pixel positions of the division points p1 and p5, which are set based on the line sensor image I, are sent to the overhead wire center point position calculation processing unit 3b via the memory M2 along with the camera parameters, and the overhead wire center point position calculation processing unit 3b calculates the real coordinates P0 (x 0 ,y 0 ) of the center point of the overhead wire 5 (Step S2).
  • the overhead wire center point position calculation processing unit 3b converts the pixel positions px1 and px5 [pix] of the division points p1 and p5 on the line sensor image I into coordinates u1 and u5 [mm] on the sensor plane shown in Fig. 5 .
  • the following computation formulae do not consider lens distortion.
  • the pixel positions px1 and px5 [pix] are first converted into sensor-plane coordinates u1' and u5' [mm] by Formula (1) below where the origin is the left end of a sensor plane 2a and ⁇ u is the width of each sensor device.
  • the sensor-plane coordinates u1 and u5 [mm] are then obtained by the conversion by Formula (2) below where the origin is the center end of the sensor plane 2a and U is the width of the sensor plane.
  • the overhead wire center point position calculation processing unit 3b After finding the sensor-plane coordinates u1 and u5 from the pixel positions px1 and px5 of the division points p1 and p5 on the line sensor image I as described above, the overhead wire center point position calculation processing unit 3b obtains an equation of a straight line L1 passing through the sensor-plane coordinates u1 and the camera center point C and an equation of a straight line L5 passing through the sensor-plane coordinates u5 and the camera center point C as shown in Fig. 5 . Note that the origin of the coordinate system is the camera center point C.
  • the straight lines L1 are L5 are each denoted as L
  • the sensor-plane coordinates u1 and u5 are each denoted as u
  • the gradient a 1 of the straight line L1 and the gradient a 5 of the straight line L5 are each denoted as a
  • the gradient ⁇ 1 of the straight line L1 and the gradient ⁇ 5 of the straight line L5 with respect to the x direction are each denoted as ⁇ .
  • the overhead wire center point position calculation processing unit 3b finds the real coordinates (x 0 ,y 0 ) of the center point P0 of the overhead wire 5.
  • Step S2 the pixel positions of the division points p1 to p5 on the line sensor image I are sent to the division point positions calculation processing unit 3c via the memory M2 along with the camera parameters as shown in Fig. 2 , and the division point positions calculation processing unit 3c finds, as shown in Fig. 3 , the real coordinates P1 (x 1 ,y 1 ), P2 (x 2 ,y 2 ), P3 (x 3 ,y 3 ), P4 (x 4 ,y 4 ), and P5 (x 5 ,y 5 ) of the division points p1, p2, p3, p4, and p5, respectively (Step 3).
  • the real coordinates P1 and P5 of the division points p1 and p5 are found.
  • the real coordinates P1 and P5 are found using the condition that they are contact points between the overhead wire 5 and the straight lines L1 and L5, respectively.
  • the real coordinates P2 and P4 of the division points p2 and p4 are points on a circle of the overhead wire 5 as can be seen in Fig. 6 , and can therefore be found as intersections of the straight lines L2 and L4 and the circle with the radius r centered at the center point P0 (x 0 ,y 0 ) of the overhead wire 5, respectively, shown in Formula (10) below.
  • the real coordinates P3 (x 3 ,y 3 ) of the division point p3 are found.
  • An equation of the straight line L3 passing through the center point P0 of the overhead wire 5 and P3, i.e., y a 3 x, is found in the same manner as those of the straight lines L2 and L4.
  • the y coordinate y 3 of the real coordinates P3 of the division point p3 can be found based on a determination on which of a part between P2 and P3 and a part between P3 and P4 is a horizontally worn part 5a and which of them is an obliquely worn part 5b. As shown in Fig.
  • the real coordinates P0 of the center of the overhead wire and the real coordinates P2, P3, and P4 of the division points p2, p3, and p4 are sent to the wear cross-sectional area calculation processing unit 3d via the memory M2 as shown in Fig. 2 , and the wear cross-sectional area calculation processing unit 3d calculates the wear cross-sectional area as shown in Fig. 3 (Step S4).
  • a wear cross-sectional area S is found as follows.
  • ⁇ 11 arcCos r ⁇ d 1 r
  • h 2 r sin ⁇ 12
  • the real coordinates P1 and P5 corresponding to p1 and p5 on the line sensor image I are different from the vertexes P6 and P7 of the overhead wire 5 in the x direction, but are rather the contact points between the overhead wire 5 and the straight lines passing through the camera center point C as shown in Fig. 6 .
  • the distance d 15 between P1 and P5 is not equal to the diameter 2r of the overhead wire (d 15 ⁇ 2r).
  • the actual wear cross-sectional area can be found if the coordinates of P2, P3, and P4 and r are known.
  • the area S 3 of the triangle P0P2P4 is given by Formula (16) because the lengths of the sides of the triangle (d 24 , r, r) are known.
  • S 3 s s ⁇ a s ⁇ b s ⁇ c
  • s a + b + c 2
  • Step S5 After the wear cross-sectional area is sent to the remaining-diameter-equivalent value calculation processing unit 3e via the memory M2 as shown in Fig. 2 , the remaining-diameter-equivalent value calculation processing unit 3e calculates a remaining-diameter-equivalent value as shown in Fig. 3 (Step S5).
  • the wear angle ⁇ of the horizontally worn overhead wire 5 A which has the same area as the known wear cross-sectional area S AB of the unevenly worn overhead wire 5 AB , is thus found.
  • the remaining diameter value of the horizontally worn overhead wire 5 A which has the same area as the known wear cross-sectional area S AB of the unevenly worn overhead wire 5 AB , or in other words, the remaining-diameter-equivalent value H of the unevenly worn overhead wire 5 AB , is thus found.
  • the remaining-diameter-equivalent value H thus found is recorded in the recording device 4.
  • the overhead wire wear measurement device and the overhead wire wear measurement method according to the present invention are not limited to the ones in the embodiment described above, and can of course be changed variously without departing from the gist of the present invention.
  • the division point positions calculation processing unit 3c calculates the real coordinates P1 (x 1 ,y 1 ), P2 (x 2 ,y 2 ), P3 (x 3 ,y 3 ), P4 (x 4 ,y 4 ), and P5 (x 5 ,y 5 ) of the division points p1, p2, p3, p4, and p5 in the above embodiment, the division point positions calculation processing unit 3c may calculate at least the real coordinates P2 (x 2 ,y 2 ), P3 (x 3 ,y 3 ), and P4 (x 4 ,y 4 ) of the division points p2, p3, and p4.
  • the worn surface of the overhead wire 5 has one horizontally worn part 5a and one obliquely worn part 5b in the embodiment described above, the worn surface of the overhead wire 5 may have a different wear shape.
  • the tensile strength of the overhead wire 5 can be accurately found even if the overhead wire 5 is the unevenly worn overhead wire 5 AB having the horizontally worn part 5a and the obliquely worn part 5b, because the remaining-diameter-equivalent value H which takes the horizontally worn part 5a and the obliquely worn part 5b into account can be calculated for the unevenly worn overhead wire 5 AB based on a remaining cross-sectional area found using the wear cross-sectional area S AB .
  • the remaining-diameter-equivalent value H can be handled in the same way as the remaining diameter value for the regular horizontally worn overhead wire 5 A , the management of the unevenly worn overhead wire 5 AB and the regular horizontally worn overhead wire 5 A can be advantageously unified.
  • the idea of finding the remaining-diameter-equivalent value H from a cross-sectional area is flexibly applicable not only to an overhead wire with uneven wear, but also to an overhead wire with a different wear shape.
  • the present invention is suitably applicable to an overhead wire wear measurement device and an overhead wire wear measurement method for finding the remaining diameter of an overhead wire by capturing an image of the lower surface of the overhead wire, which comes into contact with a pantograph, with a wear measurement camera disposed on the roof of a train and by performing image processing on the captured image of the lower surface of the overhead wire.
